It is a shag putting spaces in a path. Anyway you've done it.
However if we are talking about taskkill then there is no need to put the path at all. The /IM means "WhateverThisIs.exe" so anything containing "Rainlandar64.exe" will be stopped.
I'm not 100% sure what you want to do but you could make a .bat like this..
Not sure it is sensible (you would have to choose your programs and see if they can be stopped immediately) but you could.
taskkill /F /IM Rainlendar2.exe
taskkill /F /IM Notepad.exe
taskkill /F /IM Outlook.exe
taskkill /F /IM WinWord.exe
Anyway I'm off for a swim now - give it a go and I'll check in later.
